Mapping Windows Data Types

Notes

• Most pointer-type names begin with the prefix P or LP.
• Handles refer to a resource that has been loaded into the memory.
• Certain types may allow parameter representations different from the ones specified here.
• Pointers to simple types may need to be represented as arrays of those types.
• Representation of the Unicode-aware types such as LPTSTR or TCHAR depends on the actual type of the called function: use WideString (WideChar) when calling Unicode function version and AnsiString (Char) when calling ANSI version.
• Most Unicode versions of functions end with "W", and ANSI functions normally end with "A".
